When you press the letter "n", you see all the names of places you can go in that Skyway. When you are in the Tradewinds Skyway, and you are going to Monquista by the Stormgate to Monquista, the name floating around your screen says that you need the Indigo Windstone to use the Stormgate. It should say the Violet Windstone. When you are on top of the Stormgate, the name showing in yellow does say that the Violet Windstone is needed.

I reported the same error back in January. I am really surprised that no developer or quality assurance staff has addressed this obvious error yet.
